# Overview
Version 71.0.0 removed the setuptools.extern package and release on
07/18/2024

With this we no longer need to use `from setuptools.extern import
packaging` and we can just `import packaging`
However depending on the version of 3.10 you may still have 70.3.0 and
packaging < 24.0 so we need to navigate around the old and new.

# Test Plan

<!--
Use this section to describe the steps that you took to test your Pull
Request.
If you did not perform any testing provide justification why.

OT-3 Developers: You should default to testing on actual physical
hardware.
Once again, if you did not perform testing against hardware, justify
why.

Note: It can be helpful to write a test plan before doing development

Example Test Plan (HTTP API Change)

- Verified that new optional argument `dance-party` causes the robot to
flash its lights, move the pipettes,
then home.
- Verified that when you omit the `dance-party` option the robot homes
normally
- Added protocol that uses `dance-party` argument to G-Code Testing
Suite
- Ran protocol that did not use `dance-party` argument and everything
was successful
- Added unit tests to validate that changes to pydantic model are
correct

# Changelog

<!--
List out the changes to the code in this PR. Please try your best to
categorize your changes and describe what has changed and why.

# Review requests

<!--
Describe any requests for your reviewers here.

# Risk assessment

<!--
Carefully go over your pull request and look at the other parts of the
codebase it may affect. Look for the possibility, even if you think it's
small, that your change may affect some other part of the system - for
instance, changing return tip behavior in protocol may also change the
behavior of labware calibration.

Identify the other parts of the system your codebase may affect, so that
in addition to your own review and testing, other people who may not
have the system internalized as much as you can focus their attention
and testing there.
